Research Methods and Data Types

The video tutorial explains the differences between qualitative and quantitative research. It covers their definitions, purposes, characteristics, and methods. Qualitative research focuses on non-numerical data and understanding human behavior, while quantitative research relies on numerical data and statistical analysis. Practical examples illustrate how both approaches can be used to assess student satisfaction with online classes.

What is the primary goal of research?
